  • Upper arch structure of vehicle body lateral section
    Patent number: 10745058
    Abstract: A front pillar as a part of an upper arch structure joins an outer member and an inner member and is formed to have a closed cross-sectional structure. An upper bead and a lower bead are formed adjacent to side edge sections, each of which extends in a longitudinal direction of the inner member. The upper bead has a U-shaped cross-sectional shape. Due to the U-shaped cross section, second moment of area is increased, and thus strength of the front pillar is increased. In addition, the U-shaped cross section has a larger number of ridge lines than does a chevron cross section, and thus springback is suppressed.
